Abstract

There are three formula units in the asymmetric unit of the title compound, C14H16N2O4 center dot H2O. Molecules are linked by N-H center dot center dot center dot O hydrogen bonds into dimers with the common R-2(2)(8) graph-set motif. Between dimers, single N-H center dot center dot center dot O hydrogen bonds are formed between the other N-H group of each pyrimidine ring and the hydroxyl groups. The water molecules accept O-H center dot center dot center dot O hydrogen bonds from the hydroxyl groups and donate hydrogen bonds to the ester groups.
